How to block a payment?
If you notice an unrecognised charge on your account, you can temporarily block your card via Internet Banking (Services > Card Management > Secure Code > slide the tab next to Block Card) or Mobile App (Menu > Settings > Cards > press card icon > Lock) or contact us on 13 25 85 to discuss further.
If it is a fraudulent transaction, We would need to cancel your card and organise a replacement. Unfortunately, we cannot block a merchant from taking funds from your card.
